After watching those shows like Life After People on NGC and stuff, looks like it would be hard to avoid the other catastrophes as a result of the end of the world, let alone zombies. Like about 10 days after people disappear, without anyone to tend the nuclear reactors of the world, apparently, they would melt down spewing radioactive material in the air and all over. Zombies are easier to avoid than radiation sickness from everything that's covered in it. Sounds like a worse way to go.
